The Back on Track Calzamaglia are now also available in 100% polypropylene tessuto. The polypropylene tessuto's unique advantage is that it is both extra resistente and very effective at wicking away sweat and humidity. The superior tessuto is also much less likely to form piles than polyester due to the polypropylene tessuto's longer fibres. However, polypropylene is somewhat less elasticizzato than polyester, so one needs to choose a Taglia more carefully. Due to its excellent wicking qualities, this garment is well-suited as underwear during physical activity. The uomo's style is partially lined and has extra room in the front, but with a closed fly. The tessuto is smooth and morbido. Comes in a range of sizes (Extra Small, Small, Medium, Large, Extra Large, XX Large and XXX Large).
